Description

Austrian Patent Office AT 505 944 B1 2010-09-15

The invention relates to a shell handle, in particular for furniture with at least one movable furniture part, comprising a housing with at least one engagement opening, wherein the housing is connectable to the movable furniture part of the furniture or the housing is at least partially worked out of the furniture part and wherein the housing has a partially projecting into the engagement opening stop, and a relative to the housing against an elastic return element movable shutter, which is arranged in the housing and which rests against the stop of the housing when not operated. Furthermore, the invention relates to a furniture part, which has a shell handle and a piece of furniture with such shell handles or furniture parts.

Such depressible shell handles are already known, for example, from DE 20 2006 005 648 U1. The shutter is supported by two springs and pressed by them against the stop. The disadvantage here is that the springs can be very rigid, whereby the operation becomes unwieldy. Furthermore, by frequent use, the spring force can be adjusted or decrease, whereby the shutter is no longer optimally pressed against the stop and thus the visual impression of an almost continuous surface is no longer given. Even when the suspension is set very rigidly, opening-especially for children-can be dangerous, as fingers can be caught between the stop and the shutter by an immediately recessed spring. Also, the attachment and use of springs is a relatively expensive and expensive form of depressibly holding or placing a shutter in a shell handle.

Furthermore, from AU 597 440 B2, a shell grip is known, in which a pivotable closure flap is arranged. This flap is acted upon by a kind of leaf spring. This means that upon actuation of the flap in the direction of the interior of the shell handle, the leaf spring is flattened, while the contact point between the leaf spring and flap in the direction of the axis of rotation of the flap on the shell handle wanders. It is disadvantageous that you can not impress at any point of the flap, but only in a remote from the axis of rotation region of the flap.

An alternative way to specify a restoring element is that the restoring element is designed as a Spreizkorb, wherein a variant is already known from JP 2006-328796 A. This Spreizkorb has at least two resilient or spring-loaded Spreizfortsätze, wherein the Spreizfortsätze flower-shaped or projecting radially from a common central element. Depending on the design of this expansion basket (see FIGS. 37 and 38), it is advantageous if the expansion extensions are at an angle of between 30 ° and 85 °, preferably between 60 ° and 80 °, from the plane of the central element or base element in the direction of the closure panel protrude or the Spreizfortsätze at an angle between 95 ° and 150 °, preferably between 100 ° and 120 ° from the plane of the central element or floor element project towards the shutter.

When using a Spreizkorbes it is provided that the points away from the central element ends of the Spreizfortsätze on the shutter circular section-shaped gene. Preferably between 4 and 10 expansion processes with central element can form the expansion basket.

The object of the invention is to provide a shell handle, which avoids the disadvantages described above, whereby an improved state of the art shell grip is specified.

This object is achieved in that at the rear of the shutter at least one elastically bendable return element in the form of a suction cup, preferably made of plastic, is arranged, which presses the shutter against non-actuation against the stop, while the shutter can be moved away from the stop when actuated is, wherein the suction cup bent against the inherent rigidity, preferably flattened and / or spread, and the suction cup on actuation of the shutter at the shutter or on a bottom element of the shutter Housing or sucked on the furniture part and creates suction between the suction cup and shutter or floor element or furniture part. This embodiment is less expensive than the prior art and can avoid the pinching of fingers mainly by the, after operation relatively slowly, moving back into the stop position shutter.

According to one embodiment, it is provided that the housing comprises an integral with the housing bottom element, on which the restoring element is supported. Alternatively, however, it can also be provided that the housing comprises a separately executed bottom element, which is connected to the housing. Different embodiments of the combination options of housings and floor element are shown in figures below, with a figure shows that the bottom element is clipped on the housing via a snap-in connection.

A possible embodiment provides that the suction cup rests on the bottom element or connected thereto, preferably glued. As a result of the restoring elements present here, which will be explained in more detail later, in contrast to the prior art, there is an unobtrusive mounting of the restoring elements. If springs are used as restoring elements as in the prior art, they must be fixed with respect to the shutter or the housing, since otherwise they could adversely affect the operation of the shutter or could block this operation by tipping over or pinching the spring.

A preferred embodiment of the present invention mussel handle provides that the suction cup abuts on abutment points or one or more abutment surface (s) on the shutter or on the bottom element of the housing such that upon actuation of the shutter, the abutment points or abutment surface (s) a to the non-actuation of different size surface on the shutter or on the bottom element of the housing surrounded. Thus, the return element does not have to be in fixed connection with the housing or the floor element or the shutter, but it can be relatively freely angeordent in the housing of the shell handle and limited only by bottom element, housing and shutter in the movement.

An embodiment provides that the surface surrounded by the contact points or Anlie-gefläche (s) on the shutter is greater when operating the shutter than when not in operation.

Furthermore, it can be provided that the abutment points or abutment surface (s) of the suction cup abut circularly on the shutter, wherein the radius of these circles changed when actuated, preferably increased.

A first embodiment of this invention mussel handle and its restoring element provides that the restoring element is designed as a suction cup, wherein preferably the open side of the suction cup rests against the shutter and presses the shutter against the stop when not in operation. This embodiment of the return element causes the suction cup to suck against the closure panel when it is actuated, and negative pressure is created between the suction cup and the closure panel.

Alternatively, but could also be provided that the open side of the suction cup points in the direction of the bottom element of the housing and rests against this.

A slowly moving back into stop position shutter is achieved in that the suction cup facing surface of the shutter is roughened, which penetrates between the suction cup and shutter air. By infiltration of air, the oppression dissolves after a short time.

Short time in this context means a period of a few seconds, for example, of about 10 seconds, until the shutter rests again after pressing the stop of the housing. The necessary infiltration of air is guaranteed by the fact that the suction cup facing surface of the shutter is roughened, penetrates through between the shutter and adjacent suction cup air. In experiments, it has been found that a thin sheet of paper, which is applied to the side facing the suction cup, already supports the infiltration of air and thus the slow dissolution of the negative pressure and moving the shutter due to the inherent rigidity of the return element or suction cup in Direction rash effected.

As already indicated above, it is provided according to an embodiment that the surface surrounded by the abutment surface of the suction cup on the shutter on actuation of the shutter is about 5 to 10% larger than when not in operation. In this regard, it has been shown in tests that a suction cup used by way of example, when not operated, has a diameter of 43 mm, whereas when operated, this diameter is 46 mm. This leads to an increase of the contact surface of the suction cup on the shutter by about 7 percent.

Upon actuation, the adjacent surface of the suction cup moves from each other or migrate starting from the suction cup center apart. The abutment surface thus does not remain constant during actuation on the shutter and also the abutment points do not remain constant to each other.

In general, the restoring elements preferably have a substantially trapezoidal cross section, wherein one of the two parallels - preferably the longer of these parallels (base) - is missing, creating a cross-sectionally open restoring element. The two legs are connected to the remaining parallel in such a way that an angle change between the parallel and the respective legs takes place by actuation of the restoring element. Not to be excluded, of course, all geometric shapes (U-shaped, W-shaped, N-shaped, Y-shaped, M-shaped, Schüsseiförmig, etc.), which allow a flattening and thus caused spread. In particular, those forms are favorable, which cause an enlargement or reduction of the surface surrounded by the contact surface. Thus, although an S-shaped cross section of the return element is also possible, in this embodiment, the contact surface surrounds no surface on the shutter or the bottom element, but forms a straight line. This is similar to a spring and requires in particular a more complex fixation or stabilization in the housing or on the shutter to not affect the operability. A cross-section in the form of a horizontal S forms two mutually parallel abutment surfaces, whereby a spreading of the return element is made possible.

For the suction cup comes as a material silicone, rubber or soft PVC with a hardness of 70 Shore A in question, for example, TPE (Santoprene from Exxon), MPR (Alcryn from the company APA) and EVA (Elvax of the company DuPont) can be used.

For the Spreizkorb slightly harder plastic materials, such as polyoxymethylene (POM), polypropylene (PP) and polyamide (PA, PA6) can be used. By adjusting the material to the desired inherent rigidity of the expansion basket thus the return movement speed and thus the movement of the shutter in the direction of stop on the housing is adjustable.

It can be provided that two or more elastically bendable return elements in the form of suction cups, preferably made of plastic, are arranged on the rear side of the shutter, which press the shutter against non-actuation against the stop, whereas the shutter can be moved away from the stop when actuated is, wherein the restoring elements deformed against the inherent rigidity, preferably flattened and / or spread. Depending on the size and shape of the desired shell handle so that several suction cups, possibly together with known Spreizkörben serve as restoring elements for the shell handles.

An advantageous embodiment may provide that formed in the movable furniture part a bore, preferably milled, which forms the housing together with stop for the shutter. A preferred embodiment further provides that the bore is designed as a through hole and this is covered by the mounted on the back of the movable furniture part, preferably screwed there, bottom element ,

Alternatively, it can also be provided that the housing of the shell handle inserted in a bore of the movable furniture part, preferably glued or screwed, or the housing of the shell handle is mounted in a through hole or blind hole of the movable furniture part.

Another important aspect of this invention, for which protection is sought, is a furniture part with a shell handle according to one of claims 1 to 15. A possible embodiment may provide that the furniture part, for example a door leaf, has a frame which is formed by the housing and the bottom element of the shell handle, in which the preferably plate-shaped, adapted to the frame, shutter is operably disposed between the stop of the housing and the return elements. The housing of this shell handle can be movably mounted, for example by means of hinges, on a piece of furniture, the movement being carried out as usual in the case of shell handles by pulling on the stop.

Protection is also desired for a piece of furniture, which has a shell handle according to the invention or a just named furniture part.

Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. [0029] [0039] [0039] [0039] [0039] [0039] [0039] [0039] [0039] [0039] [0039]

Fig. 1 shows the cross section of a shell handle 1, which is inserted into a furniture part 3. This shell handle consists of a housing 4, a shutter 7, which rests against the stop 6 of the housing, and a return element 8, which is embodied according to the invention as a suction cup 8a. This sucker 8a is located at the attachment point 11 on the shutter 7. This Fig. 1 shows the shell handle 1 when not operating the shutter. 7

In contrast, Fig. 2 shows the operation of the shutter 7, whereby the suction cup 8a is flattened and prevails in the area between the suction cup 8a and 7 shutter oppression and these are held together. By corresponding roughness of the shutter surface air can penetrate into the gap between the shutter 7 and the suction cup 8a air, whereby the suction cup 8 by its inherent rigidity, the shutter 7 again in the direction of stop 6 of the housing. 4 4/22 Austrian Patent Office AT 505 944 B1 2010-09-15 moves and thereby closes the engagement opening 5.

3 and 4 show the Kippbeweglichkeit the shutter 7 in response to the engagement point or the actuation point of the shutter. 7

Fig. 5 shows a suction cup 8a from below, Fig. 6 shows this in a cross section and Fig. 7, the suction cup 8a in a view.

8 to 11 show the same cross sections as Figs. 1 to 4, wherein instead of the suction cup 8a, a return element in the known type of Spreizkorbes 8b is used. This Spreizkorb 8b is, as shown in Fig. 9, flattened and spread by actuation of the shutter 7, whereby the Spreizfortsätze 12, which lie on the abutment surfaces 11 on the shutter 7, are pressed apart. The spreading extensions 12 start from a common central element 13, which can be fastened to the housing or to the floor element or furniture part. By using a corresponding material for the Spreizkorb 8b, the speed of the return movement of the shutter in dependence on the inherent rigidity of the material used and thus the Spreizkorbes 8b can be adjusted or regulated accordingly.

Fig. 12 shows clearly the flower shape or radii of the Spreizkorbes 8b, which is shown in this case from below. Here go from the central element 13 eight Spreizfortsätze 12 or stand from it. Fig. 13 shows a cross section through the Spreizkorb 8b and Fig. 14 is a view of the Spreizkorbes. In the latter, it can be seen that the Spreizkorb 8b consists of areas of a truncated cone-shaped body.

FIGS. 15 and 16 show views of the illustrations from FIGS. 1 and 2, wherein additionally a bottom element 9 can be seen. Fig. 17 shows the housing 4, which is insertable with the shutter 7 and the suction cup 8a according to the invention in a recess of the furniture part 3, wherein the housing 4 Flaltehaken 18 has all around, whereby it holds better in the recess of the furniture part 3.

In a similar manner, FIGS. 18, 19, 20 and 24 show clamshell handles 1, wherein spreader baskets 8b are used as return elements 8.

21 to 23 show alternative forms of shell handles 1, in which a plurality of suction cups 8a according to the invention can be arranged as return elements 8.

Figs. 23 and 24 are exploded views of such clamshells having a plurality of return elements 8. In this case, the housing 4 is additionally formed by side elements 4a, whereby the simple and uncomplicated assembly of the shell handles 1 is made possible by this.

Figs. 25 to 28 now show embodiments of shell handles, which are designed as a furniture part 3, in particular as a door leaf 15. Here, the housing 4 together with the bottom element 9 forms the frame of the door leaf 15, wherein a plate-shaped shutter 7 is passively arranged between the stop 6 and the return elements 8. The return elements 8 are in turn here as a suction cup 8a, optionally together with known Spreizkörben 8b executed.

29 shows a through bore 16a through the furniture part 3. In this furniture part 3 is then (see Fig. 30), the housing 4 is inserted from above, which holds at least on the pile hook 18 on the furniture part 3. Then, from below, the shutter 7 and then the suction cup 8 a is used. Finally, the rear side of the furniture part 3 is covered by the bottom element 9 and connected by screws 10 to the housing 4.

Fig. 31 shows a blind bore 16b in the furniture part 3, in which (see Fig. 32) the housing 4, the suction cup 8a and the shutter 7 are inserted and then held with screws 10 on the furniture part 3. Fig. 33 shows a through hole which is milled into the furniture part 3, wherein the stop 6 projects into the passage opening 5, whereby no separate housing is necessary. Subsequently, as shown in Fig. 34, the shutter 7 is brought into abutment. Including a suction cup 8 a and then the bottom element 9 is attached, which holds on screws 10 on the furniture part 3.

In Fig. 35, a bore 16 in the furniture part 3 is shown. As can be seen further in FIG. 36, a bottom element 9, which is fixed on the furniture part 3 via the screw 10, is first inserted into this bore 16. This bottom element 9 in this case has all around a latching lug 9a, via which a latching nose 4a of the housing 4 can be clipped. Before clipping, however, the suction cup 8a and the shutter 7 should be used.

Fig. 37 shows a cross section of the known type Spreizkorbes 8b with the central element 13 and the Spreizfortsätzen 12, wherein the Spreizfortsätze 12 protrude at an angle of 68 ° from the central element 13. Alternatively, as shown in FIG. 38, the spreading projections 12 could project at an angle of, for example, 112 ° from the central element 13. In this way, in contrast to the illustration in FIG. 37, the area A2 would decrease on actuation of the shutter 7, which is surrounded by the abutment points 11. These angles can be chosen very freely and depend strongly on the material used and on the desired return properties.

Fig. 39 schematically shows that prior art in which a housing 4 and a shutter 7 are moved by a return member configured as a spring 19. Here, the force of the spring 19 and the force curve after actuation of the shutter 7 is linear or straight.

In contrast, Fig. 40 shows the force curve or the movement of the force in the return element in the known type of Spreizkorbes 8b, in which after actuation of the shutter 7, the Spreizfortsätze 12 about the hinge point 20 between Spreizfortsätzen 12 and central element thirteenth curved or curved and non-linear move upwards. The force thus runs in a circle around the hinge point 20 and not linearly as in a spring or for example in a foam. This force curve is an essential difference between expandable and resilient restoring element.

Fig. 41 shows the abutment surface 11 of a suction cup 8a on the shutter 7 when not operated. Now, when the shutter 7 is actuated, the area A2 increases between the abutment surface 11. Equivalent, this is also the Spreizkorb 8b, as shown in Fig. 42, instead. In this case, the circular section-shaped abutment surfaces 11 surround a smaller area A1 when not actuated than when actuated (area A2). If a spreader basket 8b is used, which is implemented as shown in FIG. 38, the area A2 decreases in comparison with the area A1.

Fig. 43 shows an alternative embodiment in which the return element 8 is arranged with the open side towards the bottom element 9 in the housing 4. In this case, it is also preferably provided that the bottom element has a roughened surface in order to ensure a slow backward movement for the shutter 7 in the direction of the rash 6 when using a suction cup 8a as a restoring element 8.

Thus, the present invention shows a visually appealing shell handle whose engagement opening is covered by a shutter, with handy, simple running, flattened and / or spreadable restoring elements in the form of a suction cup ensure comfortable handling without jamming and without complicated attachment of these return elements , 22.6
